“…The phenomenon caused by the incorporation of natural extracts in biopolymeric films may be attributed to the polyphenolic compounds presents into antioxidant extracts, forming hydrogen and covalent bonds between the hydroxyl groups of extracts with the water and hydroxyl groups presents in the starch, which would weaken the amylose‐amylopectin interactions to stabilize the starch‐network 70,71 . The antioxidant activity of pink pepper is related to the presence of polar compounds, mainly the flavonoids, anthocyanins and carotenoids, 72 which interact with starch, increase the matrix mobility and improve the plasticizer effect.…”

This study investigated the influence of grape stalk (GS) from the Bordo grape variety (Vittis labrusca L.) as a reinforcing agent, and pink pepper (Schinus terebinthifolius Raddi) extract (PPE) as an antioxidant, in cassava starch (CS)‐glycerol (GLY) films. The developed biodegradable films were characterized according to structural, barrier, mechanical, antioxidant and optical properties, as well as biodegradability and compared to both the control and blank films. Films containing a high GS content exhibited a significant increase in tensile strength (TS) values by 73%, whereas the films containing a high PPE content exhibited an important increase elongation (ELO) values by 20%, comparing to the control film (CO). The films containing 5.52% v/v of PPE presented an improving on antioxidant activity and barrier properties, leading DPPH and ABTS percentual radical scavenging activity by 51.79% and 58.18%, and decreasing water vapor permeability and solubility by expressive values of 34.11% and 79.43%, respectively. According to the results obtained in this study, the films using GS and PPE exhibited valuable characteristics and are an alternative for applications as a promising biodegradable packaging material.

“…Studies show that the NUS found in urban gardens in Salvador have the potential for complementing food, perpetuating healthy eating practices, and promoting adequate nutrition. Research with different species of these plants has revealed that they are rich in nutrients, such as proteins, fibers, vitamins, minerals, essential oils, and bioactive compounds with antioxidant capacity, which justifies the stimulus for consumption [ 17 , 48 – 56 ].…”

Background Urban agriculture has been evidenced as a food production and environmental sustainability strategy, although it faces many obstacles in Latin American countries. Additionally, in urban areas, low consumption of fruit and greenery is noticeable, along with loss in food diversity, including the neglected and underutilized species (NUS), which involve potential to strengthen local food systems. For this reason, this work has sought to map urban gardens in the city of Salvador, Bahia, Brazil, characterizing their gardeners, and to systematize information regarding food produced and the use of NUS. Methods The municipality’s urban gardens were mapped and data was collected from the gardeners. The study included two steps: (i) garden localization; (ii) on-site visits for interviews with gardeners and verification of cultivated food, destination of production, availability, and use of NUS. Results Eighteen active food gardens were located, seventeen of which participated in the study: eight (8) communal (UCG) and nine (9) private (UPG). Respondents were on average 55.76 years old, mostly (52.9%) male, working at UPG (88.9%). Women predominated in the UCG (87.5%), with higher levels of education. For 52.9% of the interviewees, the garden was their main source of income. Food produced at the urban gardens was consumed by 82.4% of the gardeners and their families. In 70.6% of the gardens, production was also sold, while 47.1% donated. During the survey, 59 NUS were found and 76.5% of respondents reported consuming 19 of the species. NUS leaves, fruits, and seeds were found to be eaten raw, boiled, or sautéed in various preparations, especially Coleus amboinicus Lour. (76.5%), Eryngium foetidum L. (35.3%), Talinum fruticosum (L.) Juss., and Pereskia aculeata Mill (both 29.4%). Occurrence and utilization of NUS did not present significant associations with the gardens or gardeners (p > 0.05). Conclusions Salvador urban gardens, even in small numbers and without government support, have produced affordable food for the local population, preserved food diversity, and the tradition of NUS cultivation and use. Thus, urban gardens are reaffirmed as relevant spaces that should be included in public policies in order to promote food and nutritional security, biodiversity, and urban environmental sustainability.

“…One of these possible biological tests is the evaluation of toxicity and biological activity using eukaryotic cells. Toxicity and antioxidant capacity assays can be carried out using Saccharomyces cerevisiae cells as a simplified biological model [17,18] . This yeast is a unicellular eukaryotic organism showing high similarity to mammalian cells in terms of protein orthology, cell signaling and antioxidant defense systems [19] .…”

Eugenia copacabanensis and Myrciaria tenella are present in restingas of the Atlantic Forest, but little information is available about their chemical and biological potential. In this context, the hexane, dichloromethane, ethyl acetate and butanol fractions from the leaves of methanolic extract were analyzed by GC/MS and HPLC‐DAD and the antioxidant potential was determined by DPPH and ABTS assays and using a Saccharomyces cerevisiae model. Dereplication allowed the identification of 68 compounds, 42 and 41 of which, respectively, are first reported here for E. copacabanensis and M. tenella. In vivo results revealed that the ethyl acetate and butanol fractions showed expressive antioxidant protection in the BY4741 and Δgsh1 strains, with greater impact on glutathione‐deficient cells. With a high diversity of phenolic compounds, these polar fractions of E. copacabanensis and M. tenella leaves are potential protectors against intracellular oxidative stress.
